constant-time-analysis

To detect timing side-channel vulnerabilities, you can analyze compiled assembly or bytecode output for dangerous instructions like division or secret-dependent branches. This Skill scans compiled cryptographic code to highlight execution time variations that leak secret data.

Constant-time analysis works with C, C++, Go, Rust, PHP, JavaScript, TypeScript, Python, and Ruby. It analyzes the compiled assembly or bytecode output across these languages to identify timing vulnerabilities in cryptographic implementations.

A timing attack exploits execution time variations to leak secret data from cryptographic operations. Dangerous instructions like division or secret-dependent branches in compiled assembly or bytecode cause measurable time differences that attackers can observe to recover sensitive information.

You can integrate timing vulnerability scanning into a CI pipeline by running the analysis on compiled code during automated builds. This Skill checks assembly or bytecode output for dangerous instructions and guides developers toward constant-time fixes before deployment.

Yes, you can analyze JavaScript and TypeScript bytecode for timing attacks alongside C, C++, Go, Rust, PHP, Python, and Ruby. The Skill examines compiled bytecode output to detect dangerous instructions that create secret-dependent execution time variations.

Static assembly analysis for timing side-channels focuses on detecting dangerous instructions like division and secret-dependent branches in compiled output. It may not capture all runtime or environment-specific timing variations and requires compiled code rather than analyzing source-level logic directly.
